Challenges of Nanoscale Magnetic Catalysts. Nanoscale Magnetic Catalysts from Past to Future

      Аннотация: Nano magnetic catalysts are one of the nanosized magnetic smart materials have proven high catalytic activity, productivity and stability in numerous catalytic applications. These nanomagnetic catalysts are possess high selectivity, high mechanical strength, controlled surface area and porosity, good resistance to deactivation and high temperature, long life time and low price. Nano magnetic catalysts generally classified into nanotubes, nanosheets, spherical nanoparticles, nanofibers, highly porous nanocomposites. The major challenge is to design and make a desired structure with suitable surface properties and biocompatibility. Extensive efforts have been made to manipulate nanosized magnetic catalysts and its combination with other structure in order to synthesize a matrix with appropriate pore size, large surface area to volume ratio. Numerous synthetic routes have been employed in elaboration of nanomagnetic catalysts such as co precipitation, impregnation, sol-gel, combustion, thermal treatment, chemical vapor deposition, and microwave plasma techniques. We described the advances and developments in the formation/synthesis of magnetic smart catalyst material.
